摘要
本文以麦克斯韦电路理论为基础对圆环天线加以分析,得到圆环天线的表面电流分布.经比对发现本文计算结果与矩量法计算结果一致,证明了本文方法的有效性和正确性.通过对圆环天线二阶MC方程的深入研究,得到了圆环天线表面电流的解析表达式,该式适于计算任意大小圆环天线的表面电流分布.本文成果对求解复杂电磁结构问题具有一定参考意义.
The paper analyzes the circular loop antenna based on the theory of Maxwellian circuits,and the current distributions of the antenna are obtained.Results are verified by moment methods,the good agreements prove the efficiency and correctness of the analysis in the paper.Through closer investigation on the second order MC equation,we deduce the current's analytical formula of the circular loop antenna.The formula suits to compute the circular loop antenna of any size.The results of the paper have certain reference significance to more complicated electromagnetic structures.
